To @ZL whom, it may con/cera:

Be it known that I, CARL HERMANN Orro STROHBACH, a subject of the Emperor of Germany, and a resident of Leipsic, in Germany, have invented a newand useful Improvement in ROpeFast-eners, (for which I have obtained Letters Patent in Great Britain, No. 8,421,

' dated J une 8, 1888; in Austriadflungary, No.

24,072 and No. 44,678, dated October28,1888; in Belgium, No. 88,427, dated September 29, 1888; in Italy, No, 24,341, dated December 3l, 1888, and in Denmark, No. 1,155, dated J anuary 81, 1889,) of which the following is a specification.

The object of thisinvention is to provide a lock or fastener for connecting the end of a rope to the standing part so as to form a loop. It is principally intended for use with Wire ropes, Where, in looping the end, the connecting of the end to the standing pai-tin a proper and secure manner is usually a tedious and difficult operation of splicing. The improved lock is intended to save the time and trouble of this operation and to form a perfectly securefastening as strong as the rope itself.

Reference being made to the accompanying drawings, Figure 1 is a sectional view of the lock with the rope looped therein. Fig. 2 is a side view thereof. Fig. 8 is a sectional View showing a slight modification in the lock. Figs. 4, 6, and 9 are detail views of one part of the lock and modifications thereof. 4 Figs. 5, 7, and 8 are detail views of another part of the lock and modiiications of the same.

The lock consists, first, of a block a, having within it a space a', extending in the direction of the length of the block, the breadth of the space in one direction being somewhat larger than the diameter of the rope and in the other direction of comparatively large breadth below and tapering` gradually toward the other end, Where it may be said to end with a breadth. equivalent to about twice the diameter of the rope. The said space is open to the outside of the block at this end through a passage a2 sufficient to receive the standing part of the rope, such passagebeing pref erably so directed that the rope without un due lexure passes down through the same curely held in the block. ple Wedge, as b in Fig. 3, and of rectangular and along one of the inclined Walls of the 5o space. At the base of the block the space a is open through two passages a3 ai, each 0f a diameter somewhat larger than that of the rope and extendingin alignment, respectively, with the tapering walls of the space a. The standingpart so-called of the rope passes along the one inclined wall of the space a', through the passage a3, and thence, suflicient rope being left to form a loop, the end is passed up through the passage a4 along the other inclined wall of the space a to the up per end thereof. The ropes thus lying against the inclined walls, respectively, Willlie toward each other, and it is obvious that by driving up a wedge between them they will be jammed outward against the Walls and se- This may be a simcross-section, or with plane faces, as shown in Fig. 5, or, preferably, with concave faces, as in Figs. 7 and 8, for the better grasp of the Wedge on the rope.

To drive the Wedge, a screw-threaded hole a5 may be made through that end of the block lyingbetween the passages ai and a4, the same being of large enough diameter to enable the wetlgc b to be passed through it into the space a. A screw-threaded bolt ci, having a square head or other suitable means for turning the same, is ttedin said hole a5, and abuts upon the base or the wedge for driving the same. The tapering' sides of the space a may be slightly curved, as shown in Fig. 3.

In place of using a wedge acting direct on the rope, a spring-wedge c, as in Figs. 4, 6, and 9, may be previously inserted and distended by the wedge h. Such a spring-wedge Would maintain a substantially stationary position, distending more or less, according to the position of the Wedge b.

On the lower end of one or each of the limbs of the wedge c maybe arranged the re-enforce or projection c', and at a suitable or corresponding place along the inclined wall or Walls of the space a may be a correspondingl hollowing h, Fig. 1.

The construction of the wedge c is visible from Figs. 4, G, and 9. It maybe a bent piece of metal or two pieces of metal riveted together at one end. It may have plane or concave faces.

Having now described my invention, I claim as new and desire to secure by Letters Patentl. A block a, having an interior space d'5 with tapering walls and passages a3 a4 aligned with said walls and adapted to receive a rope or ropes, in combination With a Wedge in said space, and means for vdriving said Wedge to jam said rope against said tapering Walls.

v2. A block a, havingan interior` space a', with tapering Walls, a passage a2, aligned with one of said Walls at the tapered end of the space, passages a and a4, aligned with .said walls at lthe broad end of` the space, adapted to. receive a looped 4rope, substantially as described, in combination with a Wedge in said space, and a screw-bolt d, bearing on said wedge for driving same for the jamming ot' said rope against said tapering walls.

The combination, snbstantiallyas illustrated and described, of a block a, having space a and passages a2, a3, and a4, as set forth, with a spring-Wedge c located in said space, a Wedge b, adapted to distend said spring- Wedge, and a screw-bolt for driving said Wedge b.

In testimony whereof I have signed this speciication in the presence of two subscribing Witnesses.
